FIG. 4 illustrates a first electronic device and a second electronicdevice performing wireless charging, according to an embodiment of thepresent disclosure.

Referring to FIG. 4, a first electronic device 410 may perform wirelesscharging with a second electronic device 420. Each of the firstelectronic device 410 and the second electronic device 420 may include acharging coil for performing the wireless charging. The charging coilmay be positioned on a rear surface of each of the first electronicdevice 410 and the second electronic device 420. For this reason, toperform the wireless charging, the rear surface of the first electronicdevice 410 may face the rear surface of the second electronic device420. A display may be arranged on a front surface of the secondelectronic device 420.

When a display 415 of the first electronic device 410 faces a specifieddirection (e.g., a user direction), a display of the second electronicdevice 420 may be positioned such that the user does not view thedisplay of the second electronic device 420. For example, the firstelectronic device 410 and the second electronic device 420 may ispositioned on a table or desk for the wireless charging as illustratedin FIG. 4. When the rear surfaces of the first electronic device 410 andthe second electronic device 420 do not face each other, the wirelesscharging may not be made or the efficiency of the wireless charging maynot be good.

The first electronic device 410 may determine a direction, which a frontsurface of the first electronic device 410 faces, through a sensorprovided therein. The first electronic device 410 may determine anarrangement relationship with the second electronic device 420 throughthe operation. For example, the first electronic device 410 maydetermine whether the front surface of the first electronic device 410faces a first direction (e.g., a sky direction) or a second direction(e.g., a ground direction), by using a gyro sensor. Alternatively, thefirst electronic device 410 may determine a direction that the frontsurface of the first electronic device 410 faces, based on whether animage associated with a user, a bright image of specified illuminance ormore, or a dark image of specified illuminance or less is captured byusing an image sensor provided on the front surface of the firstelectronic device 410.

Below, a description will be given under the assumption that it isdetermined that the first electronic device 410 is positioned on thesecond electronic device 420.

The first electronic device 410 may receive a signal, which correspondsto an event occurring in the second electronic device 420, from thesecond electronic device 420. The event may correspond to receiving anincoming call, a message, or the like. Also, the event may correspond toproviding notification that a schedule or an alarm time comes.

The first electronic device 410 may previously determine whether toreceive a signal corresponding to the event from the second electronicdevice 420. For example, the first electronic device 410 may output auser interface (UI), which is configured to determine whether to receivethe signal, through a display 415. In the case where a user inputpermitting receiving the signal is received from the user through theUI, the first electronic device 410 may receive the signal from thesecond electronic device 420 and may provide the received signal to theuser.

The first electronic device 410 may provide the user with the event,which occurs in the second electronic device 420, as a response to thesignal received from the second electronic device 420. For example, inthe case where an incoming call is being received to the secondelectronic device 420, the first electronic device 410 may inform thesecond electronic device 420 that the incoming call is being received.The first electronic device 410 may receive a user input for selectingwhether to respond to the incoming call from the user. The firstelectronic device 410 may respond to or may not respond to the incomingcall based on the user input. A way to not respond to the incoming callmay include ignoring the incoming call without any response, sending amessage that informs a terminal, which transmits the incoming call, thata current telephone conversation with regard to the incoming call is notpossible, and the like. The message that provides notification that thecurrent telephone conversation is not possible may be sent through thesecond electronic device 420 to the terminal that transmits the incomingcall.

Further, a way to respond to the incoming call may include performing aspeaker phone conversation through a speaker of the second electronicdevice 420, performing a speaker phone conversation through the firstelectronic device 410 by operating the first electronic device 410 as aBluetooth speaker, and the like. Also, it may be possible to respond tothe incoming call through a headset (e.g., a Bluetooth headset) that iswirelessly connected with the first electronic device 410 or the secondelectronic device 420.

Various ways to respond to the incoming call may verify battery levelsof the first electronic device 410 and the second electronic device 420and may allow batteries thereof to be efficiently and selectivelyoperated (or managed) according to the verified battery levels.Alternatively, the first electronic device 410 may adaptively determinewhether to make a call through a speaker or Bluetooth headset of any oneof the first electronic device 410 and the second electronic device 420,based on the battery levels of the first electronic device 410 and thesecond electronic device 420. For example, in the case where the userdecides to respond to an incoming call received in the second electronicdevice 420 through the first electronic device 410, based on a givenscenario, the user may make a call based on a speaker of one of thefirst electronic device 410 and the second electronic device 420 or maymake a call through a Bluetooth headset.

In the case where a message is received to the second electronic device420, the first electronic device 410 may inform the second electronicdevice 420 that a received message exists.

The first electronic device 410 may provide, through the display 415, aUI that is configured to notify the second electronic device 420 that areceived message exists and to query whether the user responds to thenotification. According to a user input, the message may be provided inthe first electronic device 410 and/or in the second electronic device420. The message may be provided in the second electronic device 420through a speaker by voice. Additionally, or alternatively, the messagemay be provided through a speaker of the first electronic device 410 byvoice.

At least a portion of a message, which is received in the secondelectronic device 420 and is to be provided to the user, may beprocessed. For example, in the case where the second electronic device420 receives a message, the first electronic device 410 may provide themessage received in the second electronic device 420 to the user withoutmodification, but the first electronic device 410 may provide only aportion of the message. Whether to provide the whole message or aportion thereof may be determined through a user input in the firstelectronic device 410 or may be previously determined according tosettings of the second electronic device 420. Also, in the case whereonly a portion of the message is provided, the messages may be processedin the first electronic device 410 or in the second electronic device420.

FIG. 5 is a block diagram of a first electronic device and a secondelectronic device, according to an embodiment of the present disclosure.

Referring to FIG. 5, a first electronic device 510 and a secondelectronic device 530 are provided.

The first electronic device 510 may include a sensor circuit 512, adisplay circuit 514, a first communication circuit 516, a processor 518,and a charging circuit 520.

The second electronic device 530 may include a sensor circuit 532, adisplay circuit 534, a first communication circuit 536, a processor 538,and a charging circuit 540.

The configuration of the first electronic device 510 illustrated in FIG.5 may be only one implementation and may be variously changed ormodified. For example, the first electronic device 510 may furtherinclude a user interface for receiving any instruction or informationfrom the user. In this case, the user interface may be an input devicesuch as a keyboard, a mouse, or the like, but the user interface mayalso be a graphic user interface (GUI) provided through a display of thefirst electronic device 510.

The sensor circuit 512 may sense a rotation or positioned state of thefirst electronic device 510 or a state of a circumference of the firstelectronic device 510 by using various sensors provided in the firstelectronic device 510.

The display circuit 514 may provide a variety of content through adisplay of the first electronic device 510. The content may include awidget screen, an application execution screen, a text, an image, avideo, an icon, a symbol, or the like. The screen may include a liquidcrystal display (LCD), a light emitting diode (LED) display, an organicLED (OLED) display, a microelectromechanical systems (MEMS) display, anelectronic paper display, or the like.

The first communication circuit 516 may communicate with the outside.For example, the first communication circuit 516 may receive a messageor an incoming call from a base station device. Also, the firstcommunication circuit 516 may communicate with the first communicationcircuit 536 of the second electronic device 530. The first communicationcircuit 516 and the first communication circuit 536 of the secondelectronic device 530 may communicate with each other through the basestation device or may perform local area communication with each otherwithout the base station device. For example, the local areacommunication may include BT communication, Bluetooth low energy (BLE)communication, NFC, Wi-Fi communication, MST communication, infrared(IR) communication, RF communication, Zigbee communication, and thelike.

The processor 518 may be implemented with a SoC and may include one ormore of a CPU, a GPU, an image signal processor, an AP, and a CP. Theprocessor 518 may load and process an instruction or data, received fromat least one of other elements (e.g., the sensor circuit 512, thedisplay circuit 514, the first communication circuit 516, and thecharging circuit 520), on the memory 450 and may store various data inthe memory 450.

The processor 518 may determine whether the second electronic device 530is neighboring, through the sensor circuit 512. For example, theprocessor 518 may determine whether the charging coil 522 of the firstelectronic device 510 and the charging coil 542 of the second electronicdevice 530 are positioned to correspond to each other.

The processor 518 may determine whether the first electronic device 510and the second electronic device 530 are adjacent to each other, throughin-band communication or out-band communication.

The in-band communication corresponds to communication at the samefrequency as a frequency that the first electronic device 410 and thesecond electronic device 420 use for a wireless power transfer. That is,the in-band communication may be to exchange information through asecond communication circuit 521. In magnetic induction, the in-bandcommunication may detect that the two coils are adjacent to each other,through a change in current induced in a coil (selection phase) and mayperform ping-identification/configuration-power transfer phases. Inaddition, an electronic device that receives power may further include aswitch and may receive or may not receive power, which is transmittedfrom an electronic device that transmits the power, through a switchingoperation of the switch. Accordingly, the electronic device thattransmits power may recognize an on state or an off state of the switchincluded in the electronic device that receives the power, by detectingthe amount of power that is consumed in the electronic devicetransmitting power.

The out-band communication corresponds to communication using afrequency different from a frequency that an electronic device supplyingpower and an electronic device receiving the power use to transmitpower. The out-band communication may correspond to a local areacommunication protocol (e.g., BT, Wi-Fi, NFC, or the like).

In this case, the processor 518 may provide, through the display circuit514, an UI that is configured to query whether to perform wirelesscharging. In the case where a user input requesting execution of thewireless charging is received from the user, the processor 518 mayperform the wireless charging with the charging circuit 540 of thesecond electronic device 530 through the charging circuit 520 of thefirst electronic device 510. Alternatively, the wireless charging may beinitiated after being requested through a physical button provided inthe first electronic device 510.

The charging circuit 520 of the first electronic device 510 may includethe second communication circuit 521, a charging coil 522, a matchingcircuit 523, a rectification circuit 524, an adjustment circuit 525, aswitch circuit 526, and a battery 527, each of which may perform anoperation that is previously set to perform the wireless charging. Thecharging circuit 540 of the second electronic device 530 may perform anoperation corresponding to that of the charging circuit 520 of the firstelectronic device 510.

An operation in which the first electronic device 510 processes an eventoccurring in the second electronic device 530 will be described below.It is assumed that the first electronic device 510 corresponds to thefirst electronic device 410 illustrated in FIG. 4 and the secondelectronic device 540 corresponds the second electronic device 420illustrated in FIG. 4. It is also assumed that a rear surface of thefirst electronic device 510 and a rear surface of the second electronicdevice 530 face each other and the first electronic device 540 ispositioned on the second electronic device 530.

For the first electronic device 510 to provide the UI after processingan event occurring in the second electronic device 530, verticalarrangement of the first electronic device 510 and the second electronicdevice 530 may be first determined. For example, the processor 518 ofthe first electronic device 510 may determine a direction, which a frontsurface of the first electronic device 510 faces, through the sensorcircuit 512 to provide the UI. The processor 518 may determine anarrangement relationship between the first electronic device 510 and thesecond electronic device 530 through the operation. For example, theprocessor 518 may determine whether the front surface of the firstelectronic device 510 faces a sky direction or a ground direction, byusing a gyro sensor. Alternatively, the processor 518 may determine adirection that the front surface of the first electronic device 510faces, based on whether an image (e.g., user's face image or user's bodyimage) associated with a user, a bright image of specified illuminanceor more, or a dark image of specified illuminance or less is captured byusing an image sensor provided on the front surface of the firstelectronic device 510.

The processor 518 may provide an UI, which is configured to determine anelectronic device that will transmit power and an electronic device thatwill receive power, through the display circuit 514. Alternatively, theprocessor 518 may receive information about the remaining capacity ofthe battery 547 of the second electronic device 530 throughcommunication with the second electronic device 530 and may determine anelectronic device that will transmit power and an electronic device thatwill receive power, by comparing the remaining capacity of the receivedinformation with the remaining capacity of the battery 527 of the firstelectronic device 510.

According to an embodiment, in the case where the wireless charging ismade, the processor 518 may provide a UI that is configured to determinewhether to receive a signal, which provides notification that an eventoccurs in the second electronic device 530, from the second electronicdevice 530. The processor 538 of the second electronic device 530 may bein a state in which it is previously determined that a signal thatprovides notification that an event occurs in the second electronicdevice 530 will be sent to the first electronic device 510.

The signal may be sent and received through the first communicationcircuit 516 of the first electronic device 510 and the firstcommunication circuit 536 of the second electronic device 530. Thesignal may make use of a frequency band for wireless charging betweenthe first electronic device 510 and the second electronic device 530. Inthis case, the signal may be sent and received through the secondcommunication circuit 521 of the first electronic device 510 and thesecond communication circuit 541 of the second electronic device 530.

In the case where an event corresponding to the signal is an eventproviding notification that an incoming call is received to the secondelectronic device 530, the processor 518 may inform the user that theincoming call is being received, through the display 514. In this case,caller information of the incoming call may be provided. Also, theprocessor 518 may provide a UI in which a selection may be made torespond to or decline the incoming call. In the case when a selection ismade to respond to the incoming call, the processor 518 may allowresponding to the incoming call through a speaker of the firstelectronic device 510. Alternatively, the processor 518 may request thesecond electronic device 530 to respond to the incoming call through aspeaker of the second electronic device 530, through the firstcommunication circuit 516.

In the case where an event corresponding to the signal is a receptionevent on a text message, the processor 518 may inform the secondelectronic device 530 that the text message is received. In this case,sender information of the text message may be provided. Also, theprocessor 518 may provide a UI in which a selection may be made to checkthe text message. In the case when a selection is made to check the textmessage, the processor 518 may provide the user, through the displaycircuit 514, with the whole text message or part of the text message,for example, contents of first two lines of the text message.Alternatively, the processor 518 may request the second electronicdevice 530 to provide the text message through the speaker of the secondelectronic device 530 by voice (e.g., a request may be made through thefirst communication circuit 516 or the second communication circuit512). Also, after providing the text message, the processor 518 mayprovide a UI in which a selection may be made to respond to the textmessage.

The processor 518 may provide an event corresponding to the signal so asto be overlaid on a screen provided in a display of the first electronicdevice 510. Screen information associated with the provided event may beprovided in the form of pop-up that is displayed in a predeterminedtime. The processor 518 may separately set a display area that willprovide an event corresponding to the signal. In this case, the displayarea may correspond to a mirrored version of a screen to be provided inthe display of the second electronic device 530. This operation will bedescribed with reference to FIGS. 7 to 11.

The processor 518 may differently determine whether to transfer anevent, based on a composition (or arrangement) in which the firstelectronic device 510 and the second electronic device 530 are arranged.

The processor 518 may delete the provided event from a memory of thefirst electronic device if the wireless charging between the firstelectronic device 510 and the second electronic device 530 ends. In thecase where the event is provided in a pop-up form, the processor 518 maydelete contents of a corresponding event from the memory of the firstelectronic device 510 when the popped-up event appears.

The processor 518 may change an event notification method of the firstelectronic device 510 and the second electronic device 530 into a silent(or non-audible) or sound notification method while the wirelesscharging is made.

In the case where an event notification method set in the firstelectronic device 510 or the second electronic device 530 corresponds toa vibration mode, the alignment between the first electronic device 510and the second electronic device 530 may vary by vibration when an eventoccurs in the first electronic device 510 or the second electronicdevice 530. Accordingly, when performing wireless charging, each of thefirst electronic device 510 and the second electronic device 530 maychange the event notification method into a silent or sound notificationmethod or a method of providing notification by vibration.

Also, in the first electronic device 510 and the second electronicdevice 530, one electronic device positioned under the other electronicdevice may turn off a display of the other electronic device.Accordingly, it may be possible to reduce battery consumption of anelectronic device.

Also, the wireless charging may be made when the first electronic device510 and the second electronic device 530 are mutually authenticated. Inthe case where the authentication is made, the processor 518 may makedecision as receiving the signal, without displaying a UI that isconfigured to determine whether to receive the signal providingnotification of the event. In addition, the processor 518 may skip anauthentication procedure for an electronic device that was authenticatedthrough the authentication procedure, based on a previous authenticationhistory.

The first electronic device 510 may include a user input circuit. Theuser input circuit may process a user input that is input from the user.The user input may be a touch input using a user's finger or a stylus(e.g., an electronic pen). Also, the user input may include an input forproviding an input through an electric change, although the user'sfinger or the stylus does not directly contact the screen, for example,a hover input. The user input circuit may be a touch integrated circuit(IC).

The user input circuit may distinguishably process touch inputs ofvarious kinds. The user input may include the following: touch down,touch drag (or touch move), touch release, touch hold (or long press),and drag and drop.

In this position, wirelesscharging is made between the first electronic device 610 and the secondelectronic device 620.

During the wireless charging, the first electronic device 610 mayprovide, through a display 612, an UI 614 that is configured todetermine whether to receive an event signal occurring in the secondelectronic device 620. An operation in which the first electronic device610 provides the UI 614 may be performed based on a result ofdetermining whether a front surface of the first electronic device 610faces an upper side thereof.

FIG. 7 illustrates a first electronic device and a second electronicdevice performing wireless charging, according to an embodiment of thepresent disclosure.

Referring to FIG. 7, a first electronic device 710 may be positionedsuch that a rear surface of the first electronic device 610 faces a rearsurface of a second electronic device 720. In this position, wirelesscharging is made between the first electronic device 710 and the secondelectronic device 720.

The first electronic device 710 may provide an event occurring in thesecond electronic device 720 through a display 712. The first electronicdevice 710 may distinguish a display area 714 that will provide anoperation performed in the first electronic device 710 and a displayarea 716 that will provide the event, in the display 712.
